UNITED STATES PATENT OF IC KING OTTO ST. JOHN, OF TOLEDO, OHIO. I

MANIFOLD-COPYING BOOK.

SPECIFICATION forming part of Letters Patent No. 471,724, dated March29, 1892..

Application filed November 28, 1890.

To all whom it may concern.-

'Be it known that I, KING OTTO ST. JOHN, a citizen of the United States,residing at T0- ledo,in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Manifold-Copying Books;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in manifold-copyin g books in whichblankleaves or partially-blank leaves are arranged in book form anddisposed in groups of such numbers of leaves as the desired manifold ofcopies to be produced, the said leaves being also combined with therequisite number of impres sion or carbon sheets (so called) tocorrespond in number with the aforesaid manifold of copies.

The objects of my improvements are, first, an improved method of varyingthe leaves of the book in relation to each other in their respectivegroups; second, an improved method of securing the leaves of the book,whereby they are adapted to be adj ustably and removably connected withthe holding-cover; third, an improved method of attaching animpression-sheet holder to the cover, and of constructing that part ofthe cover to which it is attached in an elastic form, whereby theimpression sheet connected with said sheetholder is adapted to besuitably applied between the leaves of the said book; fourth, animproved method of securing the impressionsheets to their holder. 1attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective View of the entireapparatus. Fig. 2 is a perspective view of the apparatus with theimpression sheet hinged to one of the sides instead of at the end of thebook. Fig. 3 is a perspective view of the cover. Fig. 4 is a perspectiveview of a portion of the cover and a portion of the book attachedtogether. Fig. 5 is a perspective partial view of the book with itsleaves in opening position. Fig. 6 is a perspective view of theimpression-sheet and its holder. Fig. 7 is an end view of the cover andits attachments without the book. Fig. 8 is a side Serial No. 372,975-(No specimens.)

View of book and cover, showing manner of attachin g theimpression-sheet wire to the cover.

Similar letters refer to similar parts throughout the several views.

The book A is made in the common tablet form, the leaves of which aremost often attached together upon one of their narrow sides, as shown inthe drawings in Figs. 1, 2, and 4. These leaves are adapted to beremovably adjusted to the cover F, as will be here- 1 inafter explained.At their lower or opening extremity the leaves of the book A are made ofvarying lengths, as shown at B in Fig. 5. These leaves are preferablydisposed in groups, each group consisting of two, three, or moreleaves,the under leaf in each group being somewhat longer than thoseabove it, as shown at BC.

D is a metal plate having the overprojecting flange D and thebase-flange D out of which flange D is formed the upwardly-projectingspring E, thus preferably and cheaply forming from one piece of metalthe parts D, D, D, and E integrally, the said plate .D being secured inany suitable manner to and forming a part of the cover F, which cover isadapt ed to be turned over in a superimposed mannor, as shown at F inFig. 3, forming the upper member of the cover F. The folding connectionG is preferably made in a somewhat springing or yielding form andadapted to hold-the impression-sheet frame H in a somewhat varyingposition by means of a hingestrap or similar device I, attached thereto,or

, by a loop, either flexible or non-flexible,such as shown in Fig. 8 atI, the combination of the said back G and hinge I adapting theimpression-sheet to be placed at any height in the bookthat is, into anyopening between the leaves of the book A-as its leaves are successivelyremoved in the process of use. This device may in a similar manner beattached to one of the long sides of the book without changing thenature of my invention, the clip J being made in a yielding form andsupplying the place of the connection in this particular.

The impression-sheet holder H is made preferably of a piece ofspring-wire bent into form shown in Fig. 6 at H, over which is foldedthe edges of the impression-sheet, as shown at K in Fig. 6. The saidfolds are thereby adapted to be secured in position by means of animpinging clip (shown at L partly in position) and adapted to be slid inthe direction of the arrow P in putting on, and in taking ofi adapted tobe slid in the opposite direction.

The operation of my invention is as follows: The book A is placed inposition, as shown in Fig. 4, by being pressed between the spring E andthe flange D, when the said spring E by its upward action impinges uponthe under side of the said book and holds it firmly against the flangeD. One of the leaves of the book is then raised to the position shown inFig. 1, when the impression-sheetis folded within the book between theleavesM and N. The upper leaf M may then be written upon with anordinary pencil, when a copy of such writing will, by means of thetransfer-sheet,

. claim as new, and desire to secure be made upon the leaf N in theusual wellknown manner. The group of sheets thus written upon are thensevered from the main book upon the perforated line 0 by the operator,who seizes between his thumb and finger the downwardly or longprojecting leaf N at or near B, (the said projecting leaf facilitatingthe operation,) and with those above quickly tears them asunder. In likemanner any number of leaves in such a group may be correspondinglyoperated upon and any required number of impression-sheets usedtherewith in an obvious manner.

' Having described my invention, what I by Letters Patent, is-

1. A manifold-copying book composed of a series of leaves, a platefolded over one edge of said book and embracing a part of the upper andlower sides of said book between overlapping flanges, to the lower ofwhich is attached a cover adapted to be folded over lengthwise acrossthe lower edge and on both sides of said book, in combination with aspring secured to said lower flange'and adapted to hold the said book inadjustable position against the upper flange of said folded plate,substantially as shown.

2. In a manifold-copying book, the combination of a series of leavessecured together in book form and to a cover adapted to be folded overlengthwise across the lower edge and on both sides of said book, towhich fold is attached a hingedimpression-sheet holder, substantially asdescribed.

3. In a manifold-copying book, an impression sheet holder havingconnected arms hinged to its cover in a flexible manner at the openingextremity of said book and consisting, substantially, of a wire I-I,having arms arranged in parallel position with respect to each other andadapted to have an impression-sheet folded thereon and held in strainedoperating position by means of impinging clamps, substantially asdescribed.

4C. In a manifold-copying'book, an impression-sheet holder havingconnected springing arms hinged to its cover in a flexible manner at theopening extremity of said book and consisting of a wire I-I, having armsarranged in parallel position with respect to each other i and adaptedto have an impression sheet folded thereon and strained by said arms intight operating position and secured in position by means 'of impingingclamps, substantially as described.

In testimony whereof I hereto afflx my signature in presence of twowitnesses.

KING OTTO ST. JOHN.
